Will u stay in a marriage…

So, my husband and i have been together for 10 years. The problem is, he is not very touchy and not affectionate to me. Idk why we lasted this long. He is a good provider, dad, and a husband to me. We only have sex once a month 😭 i wanted to say, hey lets split cause im not getting a lot of sex but im scared to hurt him. Will take any advice.

Thanks!
